Front Lighting or Back Lighting

It is fun to experiment with light.  Here is a Zinnia taken with the light coming at me, through the blossom.  I moved around until the flower was in front of a large bush.  I was on the shaded side of the bush so the background looks black.

Then I turned around and took a picture with the sun coming from behind me, over my shoulder.
Which do you like better?
Which is more dramatic?

Have fun experimenting with light!
